Unlike a spark plug that is working continuously while you
drive, glow plugs are only needed during the ignition process.
The glow plugs work by electrifying the heating element so it
heats up and emits visible light (hence the name). Intake air is
compressed before the fuel injector spray directs fuel onto the
hot tip of the glow plug during the injection of the fuel. The
injected fuel mixes with the compressed air to evaporate and
start combustion almost simultaneously, even when the engine is
cold.

Black smoke is an imbalance in the fuel mixture. Too much
fuel and not enough air. There is too much fuel added to the
mix and not enough oxygen to burn the fuel correctly. The
timing also may be advanced as opposed to retarded. Get a
timing light attach it and rotate your distributor until the
timing is correct.
There is not enough heat to burn the fuel. The unburnt fuel
travels through the exhaust and comes out the back tailpipe
as white smoke. A damaged or faulty glow plug module can
cause white smoke on engine startup. If the engine has
warmed up and there is still white smoke then there may be
one or more bad injectors, retarded timing, or a worn
injector pump.
